DRIVING-BOX.

Specification of Letters Patent.

Patented Mar. 27, ll

Application filed September 3, 1915. Serial No. 48,881.

T0 all whom z'z may concern.

Be it known that I, HENRY H. THOMP- soN, a citizen of the United States, residing at Columbus, in the county of Muscogee and State of Georgia, have invented new and useful Improvements in Driving-Boxes, of which the following is a specification.

This invention has reference to bearing boxes for the driving axles of locomotives, front trucks, trailers and the like, and it may be generally described as an improvement in driving boxes.

The invention has for its obj ect to provide a lateral plate which may be readily detached from the driving box without disassembling or removing the latter', said lateral plate iilling the space between the driving box and the face of the driving wheel, the purpose of making the plate readily detachable being to yenable the wear surface thereof to be coated with. material such as Babbitt metal for the purpose ot' compensating tor wear.

lVith these Aand other ends in view which. will readily appear as the nature oi' the invention is better understood, the same consists in the improved Construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawing,- Figure l is a sectional elevation of a driving box constructed in accordance with the invention, showing also the axle and a part of the wheel.

Fig. 2 is a top plan View of the driving box.

Fig. 3 is a top plan View showing the lateral plate detached.

Fig. i is a side view of the driving box with the lateral plate detached. I

Fig. 5 a side view of the lateral` plate .wise appropriately constructed and which are slightly tapered downwardly tor gagemont with the lateral plate 1S which is substantially U-shapcd as shown, the limbs being` provided. on their rear faces with grofwes 19 adapted to engage the flanges 1T.

rl`he lateral plate when applied in position for operation, as seen in Fig. l, straddles the axle and occupies a space betweenA the proximate faces ot the driving box and the wheel 20, its purpose being to provide a wear surface and to take up the lateral thrust of the wheel. Then the face oit .the lateral plate becomes worn it may be readily detached by simply tapping the lower ends ol' the limbs oit the plate sulliciently to loosen the same, after which the face oi the plate may be coated with Babbitt metal, a's indicated at 2l, and the plate may thenbe replaced. Clamping means, such as tur'n buttons or other appropriate clamp members 22, fitted on the screw threaded studs Q3 may be used to retain the plate in position and to prevent its being loosened by 'vilnation or other causes.

lt will be seen from the foregoing that I have produced an. extremely simple and elective means for compensating for wear between the coi'itacting faces oi? the driving box and the driving wheel, the device being of such a nature as to permit repairs to be very quickly and inexpensively made when needed, all necessity for detaching the driving box or disassembling the same being avoided.

n Having thus described the invention, what with said driving-box, and turn buttons on is` clained as new, is zsaid boxtoretain the lateral Wear plate in In combination, a driving-box having "'fpositonwitl respectto the box. dovetailed flanges tapered inwardly, a U In testimony'vvhereof I aHX my signa- `5 shlalpld lateral Wear plate; the limbs of ture in presenoeof two Witnesses.
